Did you make sure that the query dev cap wrapper unsets this bit when
proxing VF queries?
In mlx4_dev_cap:
if (mlx4_is_mfunc(dev)) {
dev->caps.flags &= ~MLX4_DEV_CAP_FLAG_SENSE_SUPPORT;
dev_cap->flags2 &= ~MLX4_DEV_CAP_FLAG2_ROCE_V1_V2;
mlx4_dbg(dev, "RoCE V2 is not supported when SR-IOV is enabled\n");
}
mlx4_slave_cap calls mlx4_dev_cap and uses the dev_caps it queried, so
we should be safe here.
if (dev_cap->bmme_flags & MLX4_FLAG_PORT_REMAP)
dev_cap->flags2 |= MLX4_DEV_CAP_FLAG2_PORT_REMAP;
MLX4_GET(field, outbox, QUERY_DEV_CAP_CONFIG_DEV_OFFSET);
